   @jgq2008303393  I guess you don's get my point, compound query cache sub-clause just because the compound query call the `IndexSearcher#createWeight`, then  the default `createWeight` cache the sub-clause. 
   
   ```
     public Weight createWeight(Query query, ScoreMode scoreMode, float boost) throws IOException {
       final QueryCache queryCache = this.queryCache;
       Weight weight = query.createWeight(this, scoreMode, boost);
       if (scoreMode.needsScores() == false && queryCache != null) {
         weight = queryCache.doCache(weight, queryCachingPolicy);
       }
       return weight;
     }
   ```
    If the  compound query  just `createWeight` and do not cache the sub-clause, and just cache itself, this problem maybe not happend?
